That to me sounds like your location of the texture files are not in the correct place, have you tried checking that and moving them to the correct location..? It might be though you'll have to reassign the texture once its moved back onto the model.
I've also had issues in the past where an imported model with the texture needs to be reassigned onto the model itself, so I did that and it all worked fine. THIS shows WHERE exactly ALL your textures should be placed before being reassigned onto the model. https://rpgbakin.com/pukiwiki_en/?Textures

I'd also recommend you join the Discord for these types of questing, this STEAM area rarely get's checked by the Bakin Community. You'd get faster and probably better help than what i've provided above, there.

Thanks for the reply Sylardean. I did add the images in resources/textures as the wiki states (made a new folder called EN where I left all my localized images) using the "add button", and those textures are shown in the list. Is there anything else I should do for the images to be added to the project?
I also joined the discord channel, thanks for the tip

Yuck discord. I was wondering why these steam forums seem so dead. I dont do discord really. Its unfortunate people prefer an unorganized mess over forums. If i want to look up a past question its near impossible on discord. So you generally just have to ask it again even if people already have and its been answered in the past.

Ive been hovering around here thinking about buying the software, but they raised the price recently with the 1.0 release so i have been waiting for a decent sale especially since it looks like theres not much of a community compared to RPG maker.
